I was born in 1980 so don't remember 83. But seeing the squad and listening to my dad (endlessly!) talk about it, they should never have gone down. Similar story in 1996 too IMO (just gave ourselves way too much to do after horrendous first 10 results). 87 and 01 both not great sides, but there was a sense of inevitability of us going down in 1987 that wasn't there in the same way in 2001. 87 a collection of (too) young boys, has-beens and never-was-beens really (and I look at that team with some fondness - still got the signed squad poster!). Despite some players in 2001 not really at top flight level (too many odd/desperate loan signings), still think they were a shade better. Some poor games; losing 1-0 at home to Leicester around Bonfire Night is a particularly bad memory. But some decent results/performances too (Everton, Leeds at home, Newcastle away).
So I'd go (best to worst)
1983
1996

1987
Interesting and being a lot older my memories are slightly different, albeit neither right nor wrong
1983 came as a complete shock, but I do recall the previous season falling off a cliff and harbouring doubts and concerns about our lack of quality, particularly after thrashings at Swansea and Wolves.
It was also patently obvious that John Bond's short termism had a shelf life, and with hindsight, he sold players who weren't good enough for where we wanted to be (Palmer Mackenzie Bennett) but were superior to where we ended up.
1987 was horrible from start to finish, and apart from Mick McCarthy's bullet header to snatch a draw against United, a fortuitous Christmas victory over Sheffield Wednesday and maybe a sense that we had 3-4 emerging youngsters, it was a depressingly familiar tale of late home defeats against Everton, Liverpool and Chelsea.
1996 only seems like yesterday, but following a disastrous start we actually played some good football, particularly at Maine Road.
We had a good nucleus of players, but appeared spineless and even mutinous when things were going wrong.
Everyone remembers the infamous time wasting when we needed another goal, but I would also argue that selling Gary Flitcroft at such a crucial time was equally disastrous
2001 was the only season when I attended every game and there was a moment during the 3-2 defeat at home to Ipswich when I feared that the Joe Royle Feelgood Factor had passed its sell by date, and the team was now running on empty fumes.
However 4-5 of those players were good enough to feature regularly in the early days of the Keegan era when City returned to the PL in a much stronger position
So my list (from best to worst)
1996
2001
1983
1987
